Find the electric force between two protons separated by a distance of 1 fermi (1 fermi = 10-15 m). The protons in a nucleus remain at a separation of this order.
Sol. Charge on each proton = a= 1.6 10^-19 coulomb Distance between charges = 10 * 10^-15 metre = r Force = kq^2/r^2 = 9 * 10^9 * 1.6 * 1.6 * 10^-38/10^-38 = 9 * 2.56 * 10 = 230.4 Netwon
